NSK Roller Bearings（Size Standards：Metric Series）

Cylindrical roller bearings are suitable for applications involving high-speed rotation because the friction between the rolling elements and the flange of the track wheel is small.

This shell-style needle roller bearing includes a needle roller and retainer installed following formation of an outer ring from a thin steel plate via precision drawing and surface curing of the corresponding raceway. Products on this page: F model

Designed so the conical vertex of the raceway surfaces of the inner and outer rings and rollers converge at one point on the centerline of the bearing.

This bearing includes an outer ring with a spherical raceway as well as an inner ring with two rows of rolling elements, and aligns itself according to the axial tilt, allowing it to bear large loads. Products on this page: 600 series

A cage that has two pieces joined together, to which surface hardening is applied after the precision press processing of a steel plate, and in which high accuracy rollers are incorporated. Many rollers are retained securely in the cage, taking large axial load, and yet rotating smoothly. Mounting space is so small that it is easy to replace a conventional sliding thrust washer.

The solid type needle roller bearing is a type of bearing that includes needle rollers and a retainer embedded in its outer ring. Products on this page: LM, NA, RL and RN models
